NEW YEAR = NEW PLANTS Characteristics of Healthy Seed Regardless of the origin or certified status of seeds, you want them to be healthy. Even certified organic, heirloom seed is useless to you if it has not been stored properly or is too old. Here are a few things you should keep in mind to ensure that you are using high-quality seeds. Storage – Whether storing seed you collected yourself or purchased from a reputable source, seed should not be stored under warm or moist conditions. Seed is best stored in dark, cool, and dry conditions. Note that seed should not come packaged in clear or seethrough packaging. Keep this in mind if you plan to store seeds in areas that are prone to moisture, such as many basements. Seed should also not be stored in the open such, as on a countertop or windowsill. This is fine if you are about to sow them, but is not effective for long-term storage. “A hybrid plant is one that “A hybrid plant is one that resulted from the cross resulted from the cross of two or more different of two or more different varieties ofvarieties plants.” of plants.” Age – Age is a tricky metric with seeds, but in general, you should always use seed that was collected from the previous season. The older the seed is, the less viable it is and the more age needs to be used to account for the reduced performance. This does not mean that seed older than one year old should be automatically thrown out; it means you should not expect the same performance per seed as younger stock. Of course, there are always exceptions. If you live in a climate with a shorter growing season, you may be better served by using slightly older seed, as it tends to mature quicker than younger seed, though often at the expense of higher yields. In nature, seed can lay dormant for many years before germinating. This is not the normal cycle for the types of annual crops that most gardeners grow. Most food and flower crops that are widely cultivated are those that spring forth from the most recent season’s seed drop. Texture – Healthy and viable seeds should not break when squeezed or feel sponge-like. They should be firm, plump (for their respective species), and have a hard casing. Any seed that is squishy or otherwise pliable should be discarded; it is likely diseased or very old. Size – Size is also a consideration with seed. It is rare that you will obtain an exact seed count when buying a package of seeds; generally, only the 142 Maximum Yield USA  |  January 2017 weight is reported on the packaging. If given the choice between “X” number of seeds per ounce or gram and some number less than “X” per the exact same weight, always go with the lesser amount. It may seem counterintuitive or that you are getting less for your money, but larger seeds (of the same species), more often than not, yield more vigorous plants than plants grown from smaller seeds. Additional Considerations After you have weighed your options and settled on your chosen varieties, there are a couple of things you should consider doing. Take note – Each packet of commercially sold seed should have a lot number or some other identifying code. Write it down somewhere or make sure to save the seed packet. You may need this
